Alberobello is a small town located in Puglia, in the south of Italy. The town is full of houses known as trulli, which are structures with conical-shaped roofs made from layers of limestone. The walls are also covered in limestone, making them white and sturdy, and they are also said to protect against UV rays, which are particularly strong in this area. These unique houses are a registered world heritage site. The pieces of this paper craft can be nested inside one another like Russian matryoshka dolls. You can also display them in size order, with the biggest one at the front, to create a miniature town with a three dimensional perspective-Canon
